Error: Unable to load summary from remote flathub: TLS support is not available

I have just started to use Flatpak on Linux Mint Debian Edition and whenever I TRY to install an application I get the above error message. I am in the Philippines as some other users with the same error stated their location. I am also using Firefox.

Now that Linux Mint has cancelled Snap how can I get Flatpak to work???

Thanks
